  • Method for controlling multi-sink/multi-path routing sensor network and sensor network using the same
    Patent number: 8660036
    Abstract: A method for controlling a multi-sink/multi-path routing sensor network and a sensor network system using the same are provided. The method for controlling the sensor network includes generating, at a sensor node, sensing data; transmitting, at the sensor node, the sensing data to a plurality of sink nodes; and forwarding, at the sink nodes receiving the sensing data from the sensor node, the sensing data to a gateway. Hence, it is possible to satisfy the reliability required in the safety-critical system with the minimum traffic. Both of the two conflicting requirements which are the reliability enhancement of the sensor network and the minimization of the network traffic in the repeated data transmission, can be satisfied adequately.
